    Fix aggregator flush method

    When no samples have been handled by the aggregator but flush method is
    called, an empty array must be returned because 'initial_timestamp' have
    not been set yet.

    Also, the pipeline always catchs exception from transformer and when an
    error occurs into a transformer the unit can not catch them.
    The patch also reraises any transformer exceptions.
